Application filed January 2, 1907.

To all whom "it may concern:

lie it known that l. ltnxanum i Mr:- (linxnss, a citizen ol the l nitcdStates, residing at VtYn-ccster, in the county at \Vorcester and State01' l\lassael1usetts, have invented certain new and useful improvementsin Looms, of which the Following is a s 'iecification.

My invention relates to looms, and particularly to that class of loomstermed taney looms, with one or more drop or change shuttle boxes at oneor both ends of the loom, and having a Knowles head motion. so termed,comprising upper and lower cylinder gears, intermediate vibrator gears,vibrator levers operated by a box pattern chain, and vibrator connectorsto the levers of the box motion, all as fully shown and described in V.S. lleissuc Letters Patent. No. 7,784.

My invention particularly relates to shuttle changing mechanian'i, andto indicating mechanism operated by the weaver, and adapted to becombined with the ordinary Knowles head motion above referred to, andother parts of a loom. ot the class re ferred to, of ordinaryconstruction, and by means of which any shuttle, having its fillingpractically or snl'istantially exhausted. may be automatically exchangedfor a shuttle having a full supply of filling of the same character orcolor, without stopping the loom.

The object of my invention is to provide a shuttle changing mechanism,and an indicat ing mechanism, to be combined with said Knowles headmotion, and the other parts of a loom, of the class referred to, of theordinary construction and operation, and

by means of which the loom may be made a continuously running loo-m, thesupply of new filling, in case of the pract' al 01" sub stantialexhaustion of filling in any of the shuttles, being controlled by thewearer, through manually operated indicating mechanism, which puts intooperation the mechanism for automatically effecting the exchange of theshuttle desired, and the supply of a new shuttle.

In my improvements, I provide two supplemental or extra, shuttle-boxesor cells, preferably arranged one directly over the other, at one end ofthe loom. The top cell is preferably for the spare shuttle, Which isSpecification of Letters Patent.

atentcd Oct. 19, I909.

Serial No. 350.336.

to take the place of the shuttle to be ex changed, and this shuttle isplaced in its cell by the weaver. The other or lower cell is preferablyto receive the shuttle to be exchanged. These two shuttle cells are additional to the ordinary shuttle cells, and in the normal operation otthe loom are pref erably not connected with the ordinary shuttleboxes orcells, to move back and forth with the lay, but are connected with themto be raised and lowered, and to main tain their same relative position.in case it is desired to exchange a shuttle, in case of the practical orsul'istantial exhaustion of the filling therein, or for any otherreason, the two supplemental shuttle cells are eon nected with theordinary shuttleboxes or cells at one end of the loom, by the weaver, tomove with them and with the lay, the weaver having first placed in thecell for the spare shuttle, a shuttle having filling therein of the samecolor or character as the filling in the shuttle to be exchanged. Theweaver then operates the indicating lever, or other device of theindicating mechanism, for the shnttlebox or cell which contains theshuttle to be exchanged, and when said shuttle-box is on a line with therace-Way of the lay, preparatory, to the picking of the shuttletherefrom, the supplemental empty shuttle cell is brought on-a line withthe race-way, to receive the shuttle to be exchanged, and then accordingto the call of the box pattern chain, the supplemental shuttle cellcontaining the spare shuttle is brought on a line with the race-way, tohave the spare shuttle picked from said cell, through the move ment ofsliding runs on the ordinary vibrator levers of the shuttle-box portionof the head motion, which form a part of my improvements, and mechanism,the action of which is controlled by a pattern indicator on the boxpattern chain, for operating, at the proper time, the mechanisms formoving the sliding runs.

My invention consists in. certain novel features of construction of myimprovements as will be hereinafter fully described.

I have only shown in the drawings detached portions of a loom of theclass referred to, having the Knowles head motion, with my improvementsin shuttle changing mechanism, and indicating mechanism applied thereto,suliicient to enable those skilled in the art to under tand theconstruction and operation tln-rcol'.

Throu h the gear connection from the lower cylinder gear shaft 12', thegear 16. fast on the pattern cylinder shaft 17 is rotated. The patterncylinder shaft 17 carries the pattern cylinder or barrel 18, Fig. forthe pattern chain, not shown, of the harness motion, not shown, and alsocarries the pattern cylinder or barrel 19, having thereon the patternchain 20, made up of bars 20 connected by links, and earryii'ig rolls20", and tubes 20', see Fig. 2, in the usual way.

All of the above mentioned parts may be of the usual and well knownconstruction in looms of the class referred to, having a plurality ofchange or drop shuttle-boxes at. one or both ends of the loom.

I will now (198(111110 my improvements, adapted to be combined. with theparts above mentioned, and by means of which the loom may he made acontinuously running loom, and any shuttle, when the filling therein ispractically or sul'istantially exhausted, may be automatically exchangedfor another shuttle with a fresh supply of filling of the same color orcharacter, without stopping the loom, through shuttle changingmechanism, and indicating mechanism operated by the weaver.

lltl

I have shown in the drawings, Fig. l to Fig. 11'', my improvements fortwo ordinary drop or change shuttle. boxes or cells at one end ol' thelooin and one box at the other cnd ot' the loom, but my improvements maybe used with two or more ordinary drop or change shuttle-boxes at eachend ol the loom; it. is only necessary to duplicate some ol the parts ofmy mechanism. In this in stance I combine with the two ordinary drop orchange slmttlwboxcs ti on the right hand end of the loom, twosupplemental boxes or cells 21, and 22, one (the upper onc,) to containpreferably the spare shuttle, to take the place of the shuttle to beexchanged, and the other to receive preferably the shuttle to beexchanged. The two supplemental shuttleboxcs or cells 21 and 22 arepreferably arranged one directly over the other, and are in thisinstance carried on the upper end of a swinging or pivotally mountedlever 23, see Fig. 16, having its upper end provided with an operatinghandle 23', to be grasped by the weaver, and its lower end, preferablymade of fork shape, see Fig. 1. pivotally mounted on a collar 2-tsecured on the lower end of the vertically moving box lifter rod 7', tomove up and down therewith. The swinging lever 23 is guided and held inposition laterally by a guide stand 23", attached to the'endtrame 1, seeFig. 1.

In the normal operation of the loom, the lever 23, carrying thesupplemental shuttleboxes 21 and 22, is preferably disconnected from theordinary shuttle-boxes G, and tends in an inclined position toward thefront of the loom, as shown by broken lines in Fig. 16, and remains inthis position, pref erably by gravity. In case it is desired to exchangeone of the shuttles when the loom is in operation, on account of thepractical or substantial exhaustion of the filling therein, then ashuttle having a filling of a similar character or color is placed inthe spare shuttle cell 21, in this instance the upper cell of the twosupplemental cells 21 and 22, and the lever 23 is moved forward by theweaver, through the handle 23', until the. two supplementalshuttle-boxes 21 and 22 are in vertical alinement with the two ordinaryshuttle-boxes or cells 6, when by means of a suitable locking device, inthis instance consisting of a spring actuated latch 25 mounted on onearm of the two guide arms 5 for the lever 23, which arms 5' extendoutwardly from the front side of the lower end of the shuttle guideframe 5, see Figs. 14 and 15, the lever 23 and the supplemental boxes 21and 22 are locked to the ordinary shuttle-boxes 6, and move up and downtherewith. The locking latch 25, see Fig. 14, is in this instancepivotally mounted on a stud 26 on one arm 5, and locks the swinginglever 28, by engaging one of its forked sides with its recessed end 25,see

Fig. l l. spring 2!) actuatcs the latch 2.3, which has a handle 25"thereon to more said latch. pin in) linnts the out ard piiolal movementol' thc inner end ot' the latch 2.3.

ln connection with the lo king latch to lock the lever 23, and hold thesupplimental boxes or cells 21 and 22 in alincnn'nt. ith the ordinaryboxes (3', l provide means for automatically operating the locking latch23. to release the lever 23 and allow it to return into its 'l'orwardposition, shown by hrolten lincs in Fig. ltl, on the l'orward heat. ofthe lay, after the spare or new shuttle has been picked 'tl'Olll itscell 21. In this in stance I employ a downwardly extending arm 25.,which is pivotally supported at its upper end, on a pin or stud 27 onone arm of the lever 23, and extends out from the front edge ol thelever, see Figs. 13, and 15. knob or projection 23 on the arm 2%,engages the outer edge ol one arm of the lever 23, see Fig. 13, andlimits the inward pivotal movement of the arm 2b. The lower end of thearm 28 is curved out 'ardly on its inner edge, and made pointed, andthere is I a cam shaped projection 25% on its outer side.

In the downward movement of the shuttle boxes. from the position shownin Fig. 1.1, to the position shown in Fig. 1G, to bring the uppersupplemental cell 21 on a line with the race-way, to have the spareshuttle picked therefrom, the arm 28, engaging at its lower end theinner curved edge 25" of the locking latch 25, see Fig. 14, is movedoutwardly, until the cam shaped projection 28 passes by the curvedextension 25' on said latch 25, and then the arm drops back into itsnormal position, as shown in Fig. 1G, with the cam shaped projection 29'under the locking latch 25, so that when the boxes are raised, after thespare shuttle is picked, the upward movement of the arm 28 on the lever23, will, through the cam projection 28' on said arm 28 engaging thelocking latch 25. move outwardly said latch, and automatically unlockand release the lever 23, and allow it with the supplemental boxes 21and 22, to return to its normal position, shown by broken lines in Fig.16, on the next forward beat. of the lay. As stated above, the uppersupplemental box or cell 21 receives the new or spare shuttle from thehand of the weaver, when the lever 23 and the boxes 21 and 22 are intheir inoperative position. and the supplemental box or cell 22 is to receivc, from the other side of the loom, the shuttle to be taken out orexchanged.

Instead of operating the lever 23 by hand as above described. to movethe supplemental shuttlc boxes 21 and 22 into operative position, and toconnect them with the ordinary shuttle-boxes 6, I may use a foot treadlemechanism, shown in Figs. 1, 15, and 16, consisting of a foot treadle orlever 31,

ha\ing a hub :31 loosely mountcd on the mental shuttle-boxes 2t and J2thereon. into their operative position. ten ion spring 35?,

attached at its other end to the hub Jill" of the arm Il l. acts toreturn said arm and the treadle incchanisni to its normal position,after the weaver has removed his foot from the treadlc. the le er 223,having the supplemental shutth hoxes or cells 21 and 22 thereon, tocause them to be connected with the ordinary drop boxes (3, the weaverthen has to indicate, through indicating mechanism, the shuttlebox whichcontains the shuttle to be exchanged for a. new shuttle, and throughindicating surfaces on the box pattern chain, the movement of themovable or sliding runs on the vibrator levers is caused to take place,through their anism. to bring the lower supplemental shuttle-box or celli on a line with the race-way of the lay at the proper time, to receivethe shuttle to he removed, and when the new shuttle called by thepattern surfacediring the upper shuttle-box or cell 21 having the spareshuttle therein, on a line with the race- 'ay, to allow the shuttletherein to be thrown across the lay into its shuttle box on the otherend of the lay, and then the loom continues to operate in the normal waywithout stopping, and the lever 23, and boxes 21 and 2:2 thereon, areautomatically moved into their forward inoperative position on theforward beat of the lay.

I will now describe my indicating mechanism, and the mechanism connectedtherewith for operating the sliding runs on the vibrator levers, tocause a change of shuttles. In this instance I have shown my indicatingmechanism, and the shuttle changing mechanism, for two ordinary dropshuttle-boxes at one end of the lay, and one box at the other end of thelay, and as the indicating mechanism for each box is simply duplicated,it will only be necessary to describe one mechanism. In this instance Ihave located the indicating mechanism, operated by the weaver, on thefront loom arch, preferably about the central portion thereof. Theindicating mechanism in this instance consists of a hand-operated lever36, having its hub 36', see Figs. 8, and 10, pivotally mounted on a stud37 secured in the upper part of a stand 38, bolted to the front. loomarch. The lever 36 has its lower handle helically coiled secured at oneend, and

.\t'terthewcavorhasmoved forward operating mechextended hub (37 of the)inion GT, l

portion in this instance provided with a lot-hing device to hold saidlever in its two extreme positions; said locking device con sists inthis instance of a pin 35] extending looscly through a. hole in thelever 36, with its inner beveled end adapted to enter a re cess ordepression lo in the stand SH, and its outer end connected with one endof a. spring actuated linger it), which is pivotally mounted on thelever 23V, and is operated by a helically coiled expansion spring ll, toact to move inwardly the pin Ht), but when pressed toward the lever lit)at its engaging end, will compress the spring I1, and withdraw the pinEli] from a hole 38' in the stand Any other suitable locking device forholding the lt\ct ill in its two extreme po sitions may be employed ifdesired.

The. lever Ill has an extension So on its hub lti, which hit." a hub orboss ltt'v there on to receive a stud l2 extending out from a split.collar 4 3) secured on one end of a connector -14, in this instance madeof tubular shape, see Fig. 10. The other end of the connector hit isconnected by an arm 4.), with a rock shaft to, in this instance madetubular, and mounted in suitable bearings, see Fig. Fast on the shaft tois an arm l8, see Fig. (l, which has a. downwardly ex tending projection4 H thereon, which is connected by a. link til to an upright latch 50,notched at its upper end, and pivotally mounted at its lower end on astud 51 on the pattern indicating lever 52, which is pivotally mountedat its outer end, and has a foot .32 thereon, which is adapted to extendover and be in the path of, and be engaged by the extended end of one ofthe bars 20' making up the pattern chain 20, see Figs. 2 and (K. Theupper notched end of the latch 5t) extends under a bar S-l, see Fig. 3,which is sup wrted in this instance on arms 55, the hubs 53 of which areloosely mounted on a shaft no. The bar {A has at.- tachcd to one endthereof the upper end of a link or connector 57, see Figs. 3, and 4, andthe lower end of said link or connector ST is pivotally attached to apin on an arm 59, the hub 59 of which is fast on. a rock shaft (10,mounted in a. bearing (51 on an arm 61, see Fig. l. The opposite end ofthe shaft 60 has fast thereon the hub (32 of an arm (32, and the upperend of the arm a2 is connected by a link 63, see Fig. 2, with a stud orscrew (34", in this instance on the hub 114- of an arm (rt fast on thesliding rod 35, having the expansion spring thereon. Said arm has a forko yoke shaped end to extend in an annular groove fit? in the hub whichis splined 011 the loosely mounted on a shaft 68. The pinion G7 mesheswith and is driven by a pinion, not shown, fast on a shaft 69, See Fig.2, which extends through to the front. of the head of the pin wheel (30,

fit

motion, and has a pinion T0 thereon, which meshes with and is driven bya pinion Tl, which is connected with and is driven by a {IllllOll TL,which meshes with and is driven )y the pattern ehaiu shat't gear lt',see l igs. 1,2, and 8. The pin wheel t'it has two pins (36" thereon,which are adapted to be moved into and out. of ei'igageinent with thestar wheel 73, having its huh loosely mounted on the battern chaincylinder slia'lt lT. The star wheel 73 has in this instance t'ast on itshub, or made a part thereof, a plate or disk 73', having coneavedportions on its periphery, corresponding to the curvature of theperiphery of the pin wheel (iii. This plate or disk 73 acts as a lock,to prevent the pin wheel 66 from moving out of engagement with the starwheel 73, after the pin wheel is moved into its operative position, anduntil it is ready to be disengaged from the star wheel, when therecesses in the plate 73' will be in proper position relative to the pinwheel (36, to allow the pin wheel to be moved away from the star wheel73, and pass by one of the concaved recesses in the periphery of theplate 73. \Vhen the pin wheel '66 is moved forward into operativeposition, it will pass by one of the concaved recesses in the peripheryof the plate 73. The star wheel 73, loose on the pattern chain cylindershaft 17, is connected with. and rotates in this instance a double cam74, which is loose ontheshaft 17. The cam 74 is shown detached in Figs.5, and 5*; said cam 74 has a cam groove 74 in one face thereof, see Fig.5, to receive a stud or roll 75 011 a cam lever 75. The cam groove 74'is so shaped, that a onehalf revolution of the cam 74, will move the camlever 75 out and in, to cause the sliding run on the vibrator lever, tobe hereinafter described, with which it is connected, to be moved awayfrom the box pattern chain, and be returned to its normal position overthe box pattern chain. The cam 74 has a. cam groove 74 on its otherface, see Fig. 5, to receive a stud or roll 76 on a cam lever 76. Thecam groove 74" is so shaped, that a one-fourth revolution of the cam 74,will move the cam lever 76 out and in, to cause the sliding run on thevibrator lever, to be hereinafter described, with which it is connected,to be moved away from the box pattern chain, and be returned to itsnormal position over the box pattern chain.

The hubs 75* and 76 of the cam levers 75 and 76, see Fig. '2, areloosely mounted on a hollow stud 65 carrying the longitudinally movingrod 65. The pin wheel 66 moves the star wheel 73, by the two pins 66 onsaid pin Wheel 66, and also moves the cam 74, onefourth of itsrevolution to o crate the cam lever 75 once, and the cam ever 76 twice,during a quarter revolution of the cam 74. The cam lever 75 is connectedby a link 77,

see Fig. 4', with a. lever 78, the hub 78' of which is fast on a rocksha't t. 5t), see Fig. 2, mounted in suitable bearings, and the other('HIII lever Tti is connected by a link 7!) with an arm 80, the hub 80'of which is fast on a sleeve 81 loose on the shaft. 5 see Fig. L. ()nthe inner end of the shaft 56 is fast. the hub 82 of an arm 82, whichhas a rounded side extension 82", see Fig. 2, on the end thereof, whichextends into the open slotted end on the sliding run 83 carried on :1vibrator lever 14, see Fig. 12, and which in this instance is attachedto said lever l l: to move loi'igitudinally thereon, by headed bolts 84-extending through elongated openings 88' in the movable or sliding run83. The run 83 has a foot 83" thereon, adapted to extend over and be enaged by the box pattern chain 20. The s eeve 81, loose on the shaft 56,has fast thereon the hub 85 of an arm 85, which has a rounded sideextension 85" thereon, see Fig. 2, which is adapted to ex tend into anopen end slot on a sliding run 86, attached to a second vibrator lever14, see Fig. 11, in the same manner as the sliding run 83 is attached tothe vibrator lever 14, and having a foot 86" thereon, adapted to extendover and be engaged by the pattern chain 20. The outer upper edge of thesliding run 86 is made inclined or cam shape, to engage a stud or pin 87extending out from one side of the run 83, see Fig. 2, and through anelongated slot in the vibrator lever 14, and raise the sliding run 83,when the sliding run 86 is moved outwardly, as shown in Fig. 11.

In Fig. 11 the second sliding run 86 is shown as moved to the left, oraway from the pattern chain 20, thus lowering the vibrator lever 14 onwhich it is mounted, and by reason of the engagement of the sliding run86 with the pin 87 on the sliding run 83, the vibrator lever 14 on whichthe sliding run 83 is mounted, is raised; this raisin of the vibratorlever 14: on which the sli ing run 83 is mounted causes the lower box 22of the supplemental boxes, to be moved to the level of the raceway ofthe lay, as shown in Fig. 1, to receive the shuttle to be exchanged whenit is thrown from the other side of the loom.

In Fig. 12, both slidin runs 83 and 86 are shown moved to the lei t, andaway from the pattern chain 20, allowing both vibrator levers 14 and 14to be dropped, and cause the upper shuttle-box or cel 21 of the twosupplemental shuttle-boxes or cells, to be moved to the line of therace-way, and allow the spare shuttle therein to be thrown across therace-way and into its shuttle-box on the other end of the lay. After thespare shuttle has been thrown across the lay, both the slid ing runs 83and 86 are moved back into their normal position over the pattern chain,to operate, through the movement of the vibrator levers, the ordinaryshuttle-boxes in e lever 30 of the indicating device, move said theusual way, and the raising of the two ordinary shuttle-boxes G at theright hand end of the loom, to bring the upper box it on a line with therace-way of the lay, will, through the release of the spring latch 25from engagement with the swinging lever 23, by the engagement of theenlarged or cam-shaped end 98 on the arm 28 with the latch 25, allow theswinging lever 23, as the lay moves forward, to be moved backward ortoward the front of the lay, as shown by broken lines in Fig. 10, andremain in that position by gravity, moving up and down with the ordinaryshuttle-boxes 0, until the weaver again moves it into engagement withsaid boxes, for another change of shuttles, either by the foot trcadlcmechanism, or by hand.

On the rock shaft 56 is fast an arm 88, see Figs. 2, and 4, which isconnected by a link 89 with an arm 90 fast on a. rock shaft 91, mountedin bearings 91 on stands 91", see Fig. 2. Fast 011 said rock shaft 91 isthe hub 92 of a forked arm 92, see Fig. 2, which has pivotally mounted,between its forked end, a latch or pawl 93, which has a projection orstud 93' on opposite sides of its inner end, and is adapted to extendinto the recessed portion of the supporting arm 92, and to form a lockor stop for limiting the down ward pivotal movement of said latch 93, asshown in Fig. 9. The other end of the latch 93 has a rounded or camshaped end 93 adapted to extend into the path of and e11- gage the armor lever 48, see Fig. 9, fast on the shaft 46. The rocking of the shaft50 in one direction, through the rotation of the cam 74, and movement ofthe cam lever 75, to cause the outward movement. of the sliding run 83on the vibrator lever 14, as above described, will, through intermediateconnections, rock the shaft 91 and arm 92 thereon, and cause thedownward movement of the latch 93, back of the arm 48, on the shaft 40,see Fig. 7. The rocking of the shaft 56 in the opposite direction, bythe continued rotation of the cam 74, and the movement of the cam lever75, will raise the latch 93, and the engagement of the latch 93 with thearm 48, see Fig. 9, will move said arm 48 and rotate the shaft 40, andthrough the arm 48, and link 49 to the upright notched latch 50 pivotedon the indicator lever 59, move back said latch out of engagement withthe bar 54, to release the bar 54 and allow it to drop, and throughconnections from said bar 54 to the arm 64 for operating the pin wheel(36, release the rod carrying said arm, and allow the spring 65' to act,to move back the rod 65 carrying said lever, and with it the pin wheel66 into its inoperative position. The rotation of the shaft 40, abovedescribed, will, through arm 45, and tubular connector 44 to the handhand lever back to its normal position, as shown at the right in Fig. 8.

In Figs. 17,18, 19 of the drawings is shown a modified construction ofthe shuttle-boxes at the right hand end of the loom. In said t'igu resare shown four ordinary shuttle-boxes, which are adapted to be dividedor moved apart in pairs, to allow of the entrance of the two sup'ilelnental boxes or cells, which may be of a similar construction tothe two supplcmental boxes 21 and hereinbefore described, and similarlymounted on a swinging lever 23. In Figs. 17 and 18, the two pairs ofordinary shuttle-boxes or cells are shown divided or moved apart, andthe two supplemental shuttle-boxes locked in position between them. InFig. 19, the two supplemental shuttle-boxes or cells are shown in theirnormal inoperative position, and the ordinary four shuttle-boxes orcells are shown moved together and locked in position. Parts similar tothose shown in the other drawings and above described, have the samecharacters of reference in Figs. 17, 18, and 19, and it will only benecessary to describe the modified construction of the ordinary dropshuttle-boxes or cells, and the mechanism for moving apart the same toreceive the supplemental boxes or cells. The bottom shaft of the loomhas in this instance mounted thereon a mutilated or master gear 96,so-termed, which meshes with and drives a mutilated pinion 97, when saidpinion, which has a sliding motion on a stationary stud 98 on the loomframe 1, see Fig. 17, is moved into the path of the teeth on the mastergear 96, through the rocking motion of an angle lever 99, pivotallymounted on a stud 100, mounted on the lower end of a stationary stand101 on the loom end or frame 1, see Fig. 19. One end of the angle lever99 is forked shape, and has pins or rolls thereon extending into anannular groove in the hub 97 on the mutilated pinion 97. The other armof the angle lever 99 is attached to a connector or rod 102 leading tothe pattern chain, or pattern indicating mechanism, not shown, on theopposite end of the loom. A crank arm 103, having a crank pin 103'thereon, is attached to and rotates with the mutilated pinion 97. Thecrank pin 103 extends into an elongated opening 104 in one arm of alever 104, centrally mounted on a stud 105,- the other arm 104" of thelever 104 is pivotally connected to the lower end of a vertically movingrod 106, the upper end of which carries the forked frame 107, see Fig.17. The upper ends of the frame 107 are adapted to extend into the pathof and engage the upper hook ends 108 on spring actuated latch locks108, which are pivotally mounted on the front side of the uper pair ofshuttle boxes, at each end thereof, and have hooks 108 on their lowerends, adapted to engage projections on the front side of the lower pairof shuttle-boxes at each end thereof, by the action 01' a spring 108',to attach the upper pair of regular shuttle-boxes or cells to the lowerpair of shuttle-boxes or cells, see Fig. 1 ,and cause said shuttle-boxesto move together. ()11 the vertically moving rod 101) is a. stud 10$)extending out. from one side thereof. in the path of and adapted toellgagc in its upward movement a cam shaped arm or plate 110, secured tothe swinging lever 23, see Fig. 17. A halt rotation of the mutilatedpinion 97 will, through the crank 103, and the crank pin 103' engagingthe lever 101, rock said lever and move upwardly the vertically movingrod 106, and with it the frame 107, to cause the upper ends of saidframe to engage and unlock the catches 108, and also to raise up the twoupper shuttle-boxes or cells (3, and allow the two supplemental boxes orcells 21 and 22 to move in between the two divided pairs of boxes, asshown in Fig. 18, and another half rotation of the mutilated pinion 97will move the lever 104 in the opposite direction, and move downwardlythe vertically moving rod 106, and frame 107 connected therewith, andthe downward movement of the shuttle.- boxes will unlock the swinginlever 23, and allow said lever, and the supp emental boxes 21 and 22thereon, to drop back into their normal position, as shown in Fig. 19,and allow the upper two cells to drop down and be locked to the lowertwo cells as shown in Fig. 19. This operation will be repeated accordingto the pattern indicating mechanism.

From the above description in connection with the drawings, theoperation of my improvements will be readily understood by those skilledin the art.

In the normal operation of the 100111, the swinging lever 23, carryingthe two supplemental shuttle-boxes or cells 21 and 22, is preferablydisconnected from the ordinary shuttle-boxes 6 on the right hand end ofthe loom, and extends toward the front of the loom, in the positionshown by broken lines in Fig. 16, and remains there, moving up and downwith the ordinary shuttle-boxes 6' on the right hand end of the loom, assuch shuttle-boxes are called during the normal operation of the loom.The relative position of the supplemental boxes 21 and 22, and theordinary boxes 6 is always maintained, so that the supplementalshuttleboxes 21 and 22 may always be moved into operative position overthe ordinary shuttle boxes 6, without regard to the position of ]saidboxes 6' relative to the race-way of the When the weaver sees that oneof the shuttles in any one of the ordinary shuttleboxes has its fillingsubstantially or practically exhausted, he takes a shuttle having acorresponding filling therein, and places it in the upper supplementalbox or cell it on the swinging lever 235. and through the haudle 23, orthe foot. treadle mechanism, moves forward said lever 2 1, to bring thesupplemental shuttle-boxes BI and 32 in line with the two ordinaryshuttle boxes (3'. 'lhe sup plemcntal shuttle-boxes 21 and 2'3 arelocked to the two ordinary shuttlwboxes (3, by thc locking mechanismwhich locks the lever 23 in its forward position. The weaver thenoperates the indicating lever 31; for the shut tle-hox which containsthe shuttle which is to be exchanged; the first indicating lever do atthe right in Fig. 1, is for the top box, or box one at the left hand endof the loom; the second indicating lever b0 for box two. the thirdindicating lever, not shown, for box three, and the fourth indicatinglever. not shown, for box four, the lowest box. The weaver moves theindicating lever 36, in this case the second lever, from its normalposition, shown by the position of the first lever at the right, in Fig.1, to its opposite position, shown by the position of the second leverat the right in Figs. 1, and S. The movement of said lever 36 moves thetubular connector 14, and through arm 45 rocks the tubular shaft 46, andthrough arm 48, and link 49, Fig. 6, moves the upright latch 50.pivotally mounted on the pattern indicating lever 52, to bring it underthe bar 54, see Fig. 6. As the pattern chain 20 revolves, the extendedend of a bar 20' raises the pat tern indicating lever 52, see Fig. 9.The raising of the lever 52, through the upright latch 50, raises thebar 54, and through link or connector 57, arm 59, rock shaft (30, arm(12, and link 63, moves the sliding rod 65, (against the action of thespring (35') earnv ing the arm 64, to move the pin wheel 66 into thepath of the star wheel 73, see Fig. 2. The partial rotation of the pinwheel 66, through the rotation of the gear 67, will give one-eighthrotation to the star wheel 73, through the engagement therewith of onepin 66", see Fig. 4, and also one-eighth rotation to the cam 74, andthrough cam lever 76, connector 79, and arm 80, rock the sleeve 81, seeFig. 2, and through arm 85, move the second sliding run 86 on itsvibrator lever 14 outwardly, and away from the attern chain 20, as shownin Fig. 11, allowing the vibrator lever 14' to drop. The outwardmovement of the sliding run 86, will, through the pin 87 on the slidingrun 83, raise the run 83, and its vibrator lever 14, thus causing thelower supplemental box 22 to be brought on a line with the race-way,when the shuttle-box containing the shuttle to be exchanged is broughton a line with the raceway on the opposite end of the loom, and theshuttle to be exchanged enters the lower supplemental box or cell 22.

The continued rotation of the star wheel 73 and the engagement of thesecond pin (3(3" therewith will give another eighth revolution to thecam T t, driven by the pin wheel W1, and will. through cam lever 76. andconnections to the sliding run 8U, more said run back to its normalposition over the pattern chain. and allow the run 93, and the vibratorlever ll on which it. is mounted. to drop to their normal position,shown in Fig. 11. to be acted on by the box pattern chain '30. If thespare shuttle to take the place of the spent shuttle, or the one to beexchanged. is called by the box pattern chain 20 home diately after thespent shuttle. has entered the supplemental box or cell 22, then thecontinued rotation of the pin wheel (36, and the. engagement of one pin(36" thereon with the star wheel 73, will give a one-eighth rotation tosaid star wheel, and also the cam 74. and, will through cam levers T5and T6, and ronnect'iolls therefrom to the sliding runs and 86, movesimultaneously both runs 83 and 8G outwardly and away from the boxpattern chain 20, as shown in Fig. 12, to allow both vibrator levers 1tand ]-'t to drop, and cause the supplemental spare shuttle box or cell21 to be brought on a line with the race-way of the lay, to have thespare shuttle picked therefrom, and then both runs 83 and 86 aresimultaneoush moved back over the box pattern chain 20, by the continuedrevolution of the cam 74:, through the rotation of the star wheel 73, bythe engagement. therewith of the second pin 6" on the pin wheel 66, andthe ordinary shuttlcboxes are operated by the box pattern chain 20, inthe usual way.

\Vhen the sliding run 83 is moved outwardly, as above described, andaway from the box pattern chain 20, the latch 93, through connections tothe rocking shaft 56, is moved downwardly, and past the arm 48, fast onthe rock shaft 46, see Figs. 7, and 9, and on the return movement of thesliding run 83 over the box pattern chain 20, the latch 93 is movedupwardly and engages the arm 48 on the rock shaft 46, and moves said arm48 and rocks the shaft l6, and through arm 48 thereon, and link 49, seeFig. 6, moves the upright latch 50 from under the bar 54, and allowssaid bar 54: to drop, and through connections to the lever (14. releasesaid lever, and allow the spring (35 to act to move the rod 65, andthrough arm 64 move the pin wheel (36 out of engagement with the starwheel 73, leaving said star wheel and the mechanism operated thereby atrest. The rocking of the shaft. 40, as above described, will, throughconnections to the indicating lever 36, return said lever to its normalposition, shown at the right in Fig. 1, as above described.

I have particularly described herein the operation of the indicatingmechanism for the second box of the four shuttle-boxes 6 at the lefthand end of the loom, but the operation of the indicating mechanism foreach of the other three boxes 6 is of the same construction andoperation.

In Fig. 2 is shown on the right of the pat tern chain 20, an extendedbar Qt) tor the pattern indicator lever for one shuttle-box at the.left, in this instance box number two, and on said pattern chain is alsoshown a half ball 20 for a second indicator lever, located on the insideof the other pattern indicator lever, for the upper box ()n the oppositeedge of the pattern chain 20 is an extended bar 20, shown in Fig. :2,for a third indi 'ator lever for box number three. and also a halt ball20" for a. fourth indicator lever for box number four. At the front ofthe loom, on the arch, there is an indicating lever for each box, andthe connectors from two levers are preferably made as a tube, and as arod extending within the tube, and a second rod, and a tube, not shown,are used for the other two indicating levers, not shown, and areconnected with and operate a mechanism similar to, and a duplicate ofthe mechanism shown in the drawings.

My improvements are adapted to be used on looms of the class referredto, having one or more drop or change shuttle boxes or cells on one, orboth ends of the loom.

It will be understood that the details of construction of myimprovements may be varied if desired. Instead of a pivoted lever 36 forthe indicating mechanism, I may use a slide, or a rotatable handle, orwheel. Instead of two ordinary boxes 6, at the right hand end of theloom, only one ordinary box may be used. The supplemental boxes or cells21 and 22 may be located on the left hand end of the loom, instead of onthe right hand end.
